GMATprep Algebra

What is 3sqrt(-89)?

If 89 wasn't prime and had a factor of 3, it would be straight forward I'd imagine, but what is the easiest method of solving this?

Thanks.

What an odd question! Is this really a GMAT prep problem, and if so, what are the answer choices as well as the original answer?
